Your summation of the situation 'bill fly' is much appreciated. There seems to me to be something "off" about the concept of MCAS as it currently exists, and seems to be causing problems for flight crews. The repetitive, insidious nature of the correction is what baffles me. I do not understand why this mismatch of "real life application" of MCAS in its intended role was not thoroughly wrung out during the test pilot phase.
